JET SELECTION
Unequal Pressure Systems
1.
If the system is supplied by a pressure pump, ensure that the pump can maintain
300kPa at the cold Inlet. If not, install a low pressure cold feed and install the mixer as if for a low pressure equal system.
2.
If the Cold pressure is ABOVE 400kPa, install the mixer without modification.
(i.e. with red nozzle as factory fitted.)
3.
If the Cold pressure is BELOW 400kPa, replace the Red Nozzle with the Blue Nozzle supplied in the carton.
a) To remove a nozzle from the mixer body fit a 6mm Allen key into the hexagon outlet of the nozzle and turn anti-clockwise until the nozzle comes free of the mixer body.
b) Fitting a nozzle is the reverse procedure to removal. The nozzle is in the
correct position when approximately 2mm of the nozzle protrudes from
the outlet of the mixer. Do not use excessive force when fitting the nozzle, it should turn freely. Screw in until just tight and then unscrew ½ a turn.
Equal Pressure Systems
Remove and discard nozzle from mixer.
